 note = {application/pdf, The tensile strength, proof stress, elongation, and hardness of commercially available titanium wire rods of 3, 4, and 5 mm in diameter, produced by the same manufacturer, have been reported to show differences. Therefore, producing dental implants while considering that commercially titanium has the same mechanical properties may be a cause of fracture. Furthermore, it has been reported that the amount of titanium elution is influenced by the combination of titanium materials with different microstructures. Manufacturers of dental implants need to understand and overcome these problems. In this study, the bending strength of commercial raw titanium materials with four kinds of thickness : 0.5 mm (T05), 0.8 mm (T08), 1.0 mm (T10), and 1.2 mm (T12), which were produced by the same manufacturer, was measured, and differences in the strength among each thickness were evaluated. As a result, the following conclusions were obtained : 1. Bending strength was highest in T08, and lowest in T12. 2. Proof stress was highest in T10, and lowest in T12. 3. Strain amount was highest in T12, and lowest in T05. 4. Hardness was highest in T10, and lowest in T12. 5. The microstructure showed that the size of crystal grains was largest in T12. 6. Titanium plate raw materials differ in mechanical properties clearly with the thickness, and the manufacturers should establish a quality control method and should offer the fixed quality of the material.},
